 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Fatty Liver in High Producing Dairy Cows Kept in Evaporative Cooling System in a Commercial Dairy Herd in Thailand) ผู้เขียน:ดร.ธีระ รักความสุข, รองศาสตราจารย์ , Sunthorn Rungruang, Theo Wensing สื่อสิ่งพิมพ์:pdf AbstractThe occurrence of fatty liver was investigated in a commercial dairy farm under evaporative cooling system in Thailand by determination of triacylglycerol concentrations in the liver. Nineteen Holstein-Friesian cows were used. Liver samples were collected at -2, 1, 2, 3, and 4 wk from parturition. At -2 wk, mean liver triacylglycerol concentration was 24.3 ? 1.0 mg/g of liver. After parturition, mean liver triacylglycerol concentration from 6 cows was lower than 50 mg/g of liver (mild fatty liver group), the mean concentration from 8 cows was between 50 and 100 mg/g of liver (moderate fatty liver group), and the mean concentration from 5 cows was greater than 100 mg/g of liver (severe fatty liver group). The results showed that 68.4% of dairy cows in this investigation suffered from periparturient fatty liver. Milk production in severe fatty liver group tended to be higher than the milk production in mild or moderate fatty liver cows. This result indicated that cows with higher milk yield tended to enter deeper negative energy balance postpartum and as a consequence had more intensive lipolysis, leading to accumulation of a greater amount of triacylglycerols in the liver. In conclusion, an evidence of fatty liver was found in high producing dairy cows, kept under cooled condition in Thailand. Before any preventive measures could be made, further research is required to study the effect of fatty liver or negative energy balance on periparturient problems, i.e. infertility, metabolic disorders, in dairy cows raised in Thai conditions. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Characterization of Chemical Properties, Lipid Profile, Total Phenol and Tocopherol Content of Oils Extracted from Nine Clones of Red Fruit (Pandanus conoideus)) ผู้เขียน:Zita Letviany Sarungallo, Purwiyatno Hariyadi, Nuri Andarwulan, Eko Hari Purnomo สื่อสิ่งพิมพ์:pdf AbstractRed fruit (Pandanus conoideus) is an endemic plant of Papua, Indonesia, traditionally known as a source of edible oil. The chemical properties of oil free fatty acid (FFA)—iodine value, peroxide value, phosphorus—the lipid profile—fatty acid (FA) and triacylglycerol (TAG) compositions—and the total phenol and tocopherol contents were determined for oil extracted from nine clones of red fruit cultivated in three area of Papua. Red fruit oil (RFO) was extracted using a chloroform-methanol solution (2:1). RFOs from nine clones had FFA of 4.3 to 9.2%, peroxide value of 0.36 to 0.84 meq per kg, iodine value of 79.3 to 85.5 g per 100 g and phosphorus content of 38 to 374 ppm. The main FAs of the RFOs were oleic (49.36–64.47 g per 100 g), linoleic (4.13–16.06 g per 100 g) and palmitic (14.11–19.21 g per 100 g), while the major TAG species were OOO/triolein (26.84–39.81%), POO/palmito-diolein (24.23–31.08%), OLO/linoleo-diolein (7.23–17.43%) and PLO/palmito-linoleo-olein (3.72–14.3%). The RFOs contained total phenol (90–742 ppm), total tocopherol (234–1,728 ppm), ?-tocopherol (52–272 ppm) and ?-tocopherol (16–287 ppm). The results of principal component analysis confirmed that the nine clones of red fruit can be divided into three groups based on their FAs and TAGs. |
